    AUTOMATIC TYRE PRESSURE MONITORING SYSTEM USING WIRELESS COMMUNICATON Prof. Mr. Prashant. G. Salunkhe 1, Mr. Harshal R. Kulthe 2, Mr. Saiprasad N. Kolhe 3, Mr. Ayaan A. Khan4 1 Guide Department of Electronics and Telecommunication, 2 3 4 Research Scholar, Sandip Foundation, SITRC College, Nasik, Maharashtra (India) ABSTRACT Tyre pressure monitoring system (TPMS) is an electronic system that monitors the air pressure of an automobile tyre and alerts the driver by displaying the real pressure or just a warning light. This project is focused on designing and developing a direct TPMS which the measurement of the air pressure is taken directly using pressure sensor. Suitable components are researched to design the prototype. Main components needed are pressure sensor, voltage-to-frequency converter, transmitter, receiver, and frequency-to-voltage converter. To power the prototype, energy is chosen through wheel rotation. Main components need to be calibrated to ensure the consistency and precision of the prototype in reporting the pressure. Calibration for pressure sensor is performed by simply applying a known value of pressure and the output voltage is measured. For voltage-to- frequency and frequency to-voltage converters, a known value of voltage or frequency is applied and the output is monitored using voltmeter and oscilloscope. The results show promising data by proving the relationship between the input and output for each component. As for the conclusion, although there are many problems and limitations faced, this prototype is a promising product in real world application. I. INTRODUCTION Every year, many accidents occurred and for certain cases, accidents are caused by under-inflated tyres.

NEED FOR TIRE PRESSURE MONITORING BACKGROUND • A tire-pressure monitoring system (TPMS) is a system that detects a tire that has low inflation pressure and warns the driver. • Because a run-flat tire is designed to be driven a limited distance and at limited speed after it loses air pressure, a method of alerting the driver had to be found. • There were two systems used, indirect and direct, until the 2008 model year when the use of direct- reading pressure systems was required by law.

  • TPMS Glossary of Terms Courtesy of Continental Commercial Vehicles & Aftermarket
    TPMS Glossary of Terms Courtesy of Continental Commercial Vehicles & Aftermarket Tire Pressure Monitoring System (TPMS) Tire pressure monitoring systems (TPMS) provide real safety and economic benefits for motorists. By helping drivers to maintain proper tire inflation, TPMS can help improve ride and handling, reduce stopping distances and the potential for hydroplaning, increase MPG and extend tire life. TPMS is designed to monitor the air pressure in a tire and send a warning to the vehicle’s on-board monitoring system when the pressure drops below a preset limit. In addition to the different types of systems and variety of components found in today’s TPMS-equipped vehicles, there are also a wide variety of terms used to describe various TPMS functions and service requirements. This glossary will help you to define and better understand these industry terms. Disclosure: While this TPMS glossary of terms may contain useful reference information for the global TPMS service marketplace, it is specifically intended for the USA, primarily due to legislation references. Glossary of TPMS Terms 2 Glossary of TPMS Terms Term Definition Activate See “LF low frequency trigger (wake) signal” definition. Adjustable valve stem A TPMS sensor valve stem that pivots to accommodate different wheel rim contours and the valve hole angle of the rim. Advanced system Typically a TPMS system with a dashboard display that shows each tire’s pressure by wheel location (left front, right front, etc.). Advanced TPMS systems may also display individual tire air temperatures. Aftermarket sensors Sensors that are available as replacements for the vehicle’s original equipment. Includes OE replacement sensors, cloneable sensors, configurable sensors, multi-application sensors and programmable sensors.

    LOW POWER TIRE PRESSURE MONITORING SYSTEM A Thesis Presented to The Graduate Faculty of The University of Akron In Partial Fulfillment of the Requirements for the Degree Master of Science Sravanthi Goparaju December, 2008 LOW POWER TIRE PRESSURE MONITORING SYSTEM Sravanthi Goparaju Thesis Approved: Accepted: __________________________ __________________________ Advisor Department Chair Dr. Nathan Ida Dr. Jose A. De Abreu-Garcia __________________________ __________________________ Committee Member Dean of the College Dr. James Grover Dr. George K. Haritos __________________________ __________________________ Committee Member Dean of the Graduate School Dr. George Giakos Dr. George R. Newkome __________________________ Date ii ABSTRACT Power management is considered to be an important aspect in designing battery operated Tire Pressure Monitoring Systems (TPMS) as it helps to prolong the lifespan of the battery. There are several methods that can be used to design a low power tire- pressure and service monitoring system. One of the most common methods for power reduction is the duty cycle method. This thesis suggests an idea of implementing the TPMS in combination with a separate Radio Frequency Identification (RFID) circuit, especially a very low power (active or passive) RFID whose sole purpose is to detect the interrogating signal. This RFID circuit which can operate at a typical frequency of 125 kHz is used to turn ON a higher power transmitter which is initially in SLEEP state and soon after entering the active state performs the communication, updating, etc. Once the desired task is completed, the high power transmitter returns to SLEEP state or is turned off until the next interrogation. The implementation of SLEEP mode to minimize power consumption is discussed in detail and the currents consumed by the microcontroller in SLEEP and ACTIVE modes are measured and recorded.
